Gods choice ( Matthew 13 v 55 )

I remember when my then first  wife who was attending Bible college told me how a lecturer told of an experience he had in Africa which he was ashamed of. He was in a certain home when a native person came to the front door,and person who owned the home told him to go round the back.The lecturer felt he should have said something but he didn't,he deeply regretted this.I went to a different Bible college, I had completed my 3 yrs training, but no doors had opened for me into ministry,so I went to that dear brother for advice,I introduced myself ,but his first words were to criticise the way I spoke, to me it was so out of place in its context,no help was offered or advice given.It appeared that that dear brother had failed to learn anything from his African experience.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         ''Brothers, think of what you were when you were called. Not                                                                  many of you were wise by human standards; not many were                                                                    influential; not many were of noble birth.But God chose the                                                                    foolish things of the world to shame the wise; God chose the                                                                  weak things.....the lowly things...the despised things,......so that                                                               no one may boast before Him. (  1 Corinthians 1 v 26 - 29 )
